'SPECIFICATION forming part of Letters Patent No. 3212.340, dated July 14, 1885.

Application filed April 27, 1885.

To all whom, t may concern:

Be it known thatv I, EDWARD M. ALLEN, a citizen of the United States, residing, at Stafford, in the county of Harfordv and State `of llIaryland,.have invented certain new and useful Improvements in Wagon-Brakes, of which the following is a specification, reference being had therein to the accompanying drawings.

" My invention relates to improvements in Io wagon-brakes, and is designed Vto producea brake that willlock by the weight ofthe body or load and unlock by the draft of the horses.

The improvement consists, essentially, in the employment of a divided axle having an I 5 oscillatory motion, movable hounds and perch connected therewith, and the manner of connecting and operating the parts, the whole of which are fully hereinafter set forth, 'reference being `had to the annexed drawings, in

which- Figure l represents a longitudinal section to one side of the center; Fig. 2, a similar section to the other side of the center; 1Fig. 3, a front elevation with parts in section; Fig. 4, a

lateral section in front of the rear axle; Fig.

5, a vertical section through the swivel.

The body A has strips or cleats B on each side, between which snugly lit uprights or standards C on the bolsters D. This arrangement, while allowing the removal of the body, keeps the said body and the holsters in rigid connection, preventing the said holsters from rocking or twisting.

Secured pivotally to the rear bolster, by

means of suitable bearings, is the upper section of a divided axle, E. This axle, as well as the front axle, F, has a lower section, preferably one-third as far below the spindle G as the upper section is above it.

To the center of the axle E, and extending from one section to the other, for the purpose of strengthening and bracing them, is a double stirrup or strut, H, the lower portion of which guides a lower reach or perch, I, an upper 4 5 perch, K, connecting and bracing the bolsters.

\. The rear hounds are connected to the perch I, and pivotally connected to the lower section of the rear axle, and to the rear thereof carry stops L, which engage against the upi 5o per section as the horses draw, preventing too (No model.)

4great play of the said axle. Springs M, projecting beyondthe contactpoints of the stops,

break the shock of contact.

A hook, N, attached to the part of the rear axle, carrying one of the spindles, and engaging in a perforated plate, O, attached to the side of the body, serves to keep the brake locked or unlocked, when so desired.

On the rear hounds are two cross-pieces, l?,

with the brake-bar R between them.

At the ends of the pieces P are perforated plates S, through which pins pass, en# gaging in eyes T in the brake-har. By this means thesaid brakebar may be adjusted to or from the wheels, either to take up wear or to make the travel of the brake longer.

To the front bolster is a swivel, U, in which the upper section of the front axle has pivotal bearings.

On each side of the swivel are stirrups V, connecting the two sections of the axle. To the lower section between the said stirrups is a U-plate, WV, to which the reach or perch I4 is pivoted. By this means the front axle is allowed to oscillate and also to swing as on a fifth-wheel.

To the front hounds are secured hangers X, the lower ends of `which are pivoted to extended stirrups Y, near the ends of the divided portion of the axle. This gives sufficient leverage to overcome the weight of the body and load in unlocking the brake.

At the various pivotal connecting points on the axles collars are either formed'or shrunk on, thus preventing the parts from having lateral play. l

In operation the weight ofthe body and load Y 1. In a wagonbrake, a'n oscillating or rocking axle connected to and operating the brake, substantially as and for the purpose specified.

2. In a Wagon-brake, an oscillating or rocking axle connected to the Wagon-body and to the brake, and automatically operating the same, substantially as and for the purpose specified.

3. In a wagon-brake, an axle having one section or portion three times as far above the axis thereof as the other section or portion is below the said axis, substantially as and for the purpose speciiied.

4. In a wagon-brake, a divided front and rear oscillating or rocking axle, in combination with the bolsters secured by suitable bearings to the upper sections of the axles and hounds and perch secured by suitable bearings to thelower sections, the rear hounds supporting the brakebar, substantially as and for the purpose specified.

5. In a wagon-brake, an oscillating or rocking front axle pivotally connected and swivel ed to the perch and front bolster, substantially as and for the purpose specified.

6. In a wagon-brake, in combination with oscillating or rocking axles connected by perch and hounds, xed bolsters to which the axles are connected, said bolsters being held in. position by an additional or supplementary perch, substantially as and for the purpose specified.

7. In a wagon-brake, a brake or lock-bar, adj ustably held to the rear hounds relative to the wheels by means of pins passing through perforated plates on cross-pieces secured to said hounds, and engaging with said bar, substantially as and for the purpose specified.

8. In a Wagon-brake, an oscillating or rockl ing stirrups or struts supporting and strengthening the said axle, substantially as and for the purpose specified.

12.' In a wagon-brake, in combination with a divided axle, extended struts or stirrups on the said axle and hounds having hangers which are pivoted to the said struts, substantially as and for the purpose specified.

13. In a Wagon-brake, a divided axle pivoted to the hounds and bolsters and having collars shrunk or formed on it to prevent lateral motion in the pivotal bearings, substantially as and for the purpose specified.

14. In a wagon-brake, in combination with a divided axle, a hook secured to the axial portion of said axle and engaging adjustably with the body, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
